Hans Stein: Use of Feed Technology to Improve the Nutritional Value of Feed Ingredients Fed To Pigs

May 05, 2015

Dr. Oscar Rojas is a recent Ph. D. recipient from the Stein Nutrition Lab. In this podcast, he presents his doctoral research into the use of various feed processing technologies to improve the nutritional value of feed ingredients fed to pigs. Topics include:

Determining the concentration of DE and ME and the digestibility of P, AA, and starch in corn grain that was ground to different particle sizes and fed to growing pigs

Tests of the hypotheses that the addition of dietary lipids can be reduced as corn particle size is reduced without affecting growth performance or carcass characteristics, and that caloric utilization of corn fed to weanling pigs is increased if particle size of corn is reduced

Effects of extrusion and pelleting on energy and nutrient digestibility in diets with different levels of fiber fed to pigs

Effects of chemicals, physical, or enzymatic treatments on concentration of ME and digestibility of energy in DDGS fed to pigs

Video: How We Pick Sheep For Use As Breeding Stock

In this episode of our sheep farming vlog at Ewetopia Farms, we’re diving deeper into one of the most important parts of raising purebred sheep — selecting our breeding stock. ?? This episode is a direct follow-up to our popular video “You Be The Judge,” where we invited viewers to help evaluate our rams. We read through your comments, shared your insights, and now we’re responding! Arnie and I go over what we agreed with, where our opinions differed, and what we look for when choosing both rams and ewes to carry on our genetics. Breeding decisions at Ewetopia Farms aren’t just about looks — they’re about structure, performance, temperament, and the future of the flock. Whether you’re building your own breeding program or just curious how we make these decisions, today’s discussion offers a rare look inside the thought process behind improving a flock year after year.
